I’ve been running a Sionics NP3-coated BCG for a little while now in my main carbine.  Thought I would take some pics and show how well it cleans up.
I had approximately 500 rounds of IMI M193 ball through this M4 since the last cleaning. I usually go much longer than this before I clean, but wanted to see how well she would clean. I’ll admit, I didn’t think about taking pics until I had already started; originally I was just doing this for my own personal knowledge.
In this first pic, all I have done is wipe it down with a blue paper towel, just like the one it’s sitting on. There is absolutely no carbon fouling anywhere on the outer surfaces of the BCG; anything that looks like carbon is either a shadow or a reflection on a shiny portion. All the carbon wiped off easily with a paper towel.
	
		
			
		
		
	
	
		
			
		
		
	
Another pic, better showing the bolt and lugs.
	
		
			
		
		
	
Face of the bolt. The parts on the flat faces of the lugs that looks like carbon is actually a reflection on the shiny section.
